Description
For the design of warm-air conveyor driers and of ventilated bins to be used for grass seeds drying, certain parameters of the drying characteristics under varying conditions must be known. Investigations in a climatized chamber with seeds from different plant species at varying bulk height, inlet air temperature, and rate of air flow have shown the drying characteristics of a layer to be quite similar to those of a single drying crop. The curve of the drying velocity can be approximated by two branches, a first branch with constant drying velocity and a second straight-lined declining branch. The whole operation is determined by 3 parameters: initial drying velocity, equilibrium moisture content, and time constant.
